1. identifiedAug 14, 2026, 7:58 AM UTC

   A change rejects unknown TTS language regions, e.g. `hi-in` is rejected since an ISO 3166-1 alpha-2 country code is expected. We are working on rolling back this change. To correct the issue immediately, avoid sending the country code or send a corrected country code such as `hi-IN`.
